Update: August 17th, 2012
Langford Lake Residents - Please Note:
On Sunday August 19, 2012, the new aerator will be installed at Langford Lake.
Please be advised that for the first couple of days after the aerator is turned on, you may notice a "rotten egg" smell similar to natural gas. This is due to the release of stale gases from the lake bottom as the aerator is performing its function.
We would request that residents and users of the lake please stay away from the aerator as it purges the bottom of the lake.
UPDATE: August 16, 2012
The City has been informed that the Sikorsky Skycrane is in for repairs and will not be available to lift the aerator into the lake. The lift will now take place as scheduled on Sunday, August 19th between 8-10 AM with a Kamov helicopter.
UPDATE: August 16, 2012
Aerator has been reassembled and is now ready for installation into Langford Lake.
UPDATE: August 15, 2012
The new Langford Lake areator has arrived and is being put together.
UPDATE: August 14, 2012
The Sikorsky Sky crane will be arriving between 9:30 -10 AM Sunday morning, August 19th and the installation of the aerator into Langford Lake will occur shortly thereafter. This is a very big helicopter so we ask that NO ONE be on the lake at this time.
UPDATE: August 10, 2012
The construction of the new hypolimnetic aerator is almost complete (see above photo link). It will be airlifted into Langford Lake on Sunday, August 19th. Check the City's website August 15th-17th for the time of the airlift.
On July 24th, divers from Advanced Subsea Service Ltd. will be removing the old aerator from Langford Lake in preparation for the new aerator. The divers will also be installing 4 large concrete anchor blocks at the existing aerator site. Once the anchors are in place they will be marked by floating buoys that will remain in place until the aerator is installed. We ask that all residents and users of the Lake please refrain from going near this location.
It is anticipated that the new aerator will be installed in the mid-late August. The new hypo limnetic aerator (see attached rendering) weighs approximate 12,000 lbs. (5.443 metric tonnes) and will be airlifted into Langford Lake using a Sikorsky Sky-crane. Please check back for updates regarding the installation of the aerator.
